Gluon dissociation of J/ψ beyond the dipole approximation Academic Article uri icon

abstract

  • Using a nonrelativistic potential model, we calculate the cross section for the leading-order gluon dissociation of J/ψ by including the full gluon wave function. We find that the resulting cross section as a function of gluon energy is reduced by about a factor of three at its maximum value compared to that calculated in the dipole approximation that is usually adopted in theoretical studies. The effect of the reduced cross section on the J/ψ dissociation width is, however, small at finite temperature. © 2013 American Physical Society.
